Accessibility checking

The AccessibilityCheck
class allows you to use your existing test code to test for accessibility
issues. As you interact with a View during a test, the accessibility test
framework runs checks automatically before proceeding. Just import the class and
add the following code to your setup methods annotated with @Before:

This will cause accessibility checks to run on a given view every time you use a
ViewAction from the ViewActions class. To instead run these checks on all
views in the hierarchy, use the following logic:

Kotlin

AccessibilityChecks.enable()
.setRunChecksFromRootView(true)

Java

AccessibilityChecks.enable()
.setRunChecksFromRootView(true);

When first enabling checks, you may encounter a number of issues you may not be
able to deal with immediately. You can suppress these errors by setting a
matcher for the results that you would like to suppress. Matchers for
AccessibilityCheckResult appear in
AccessibilityCheckResultUtils
within the accessibility test framework. For example, to suppress all errors for
a view with the ID R.id.example_view:
